Presynaptic but not postsynaptic Ca2+ increase is required for l-CCG LTD.A, Summary of eight experiments showing that the membrane-permeable Ca2+ chelator BAPTA-AM (100 μm) suppressed synaptic transmission and blockedl-CCG LTD. B, Superimposedtraces taken immediately (1 min) and 30 min after the impalement of cell with a BAPTA-containing electrode to show the block of afterhyperpolarization. Electrode was filled with BAPTA (50 mm) as described in Materials and Methods.C, LFS LTD but not l-CCG LTD was blocked by intracellular BAPTA.
